Energy or Power – Corvus Energy Orca™ ESS Product Line Meets Both Differing Demands

Energy or Power – Corvus Energy Orca™ ESS Product Line Meets Both Differing Demands

This is the second article in a series highlighting the five remarkable design features incorporated into Corvus Energy’s Orca™ Energy Storage System (ESS) product line design—a design that earned Corvus Energy the Electric & Hybrid Marine Technology 2017 Innovation of the Year award, as well as the BC TIA Technology Impact Award for Excellence in Product Innovation.

Fundamental to Orca’s design is the recognition that there are multiple uses of ESS systems, and the performance requirements are significantly different depending on its use. “Even among the vessel types that are installing ESS today, there are differing requirements for what the products must do,” explains Sean Puchalski, Vice President at Corvus Energy. “These differences are mostly in terms of whether the vessel needs an ESS that can discharge evenly over an extended period of time (think all-electric ferry) or whether the vessel needs an ESS that can absorb and support large fleeting transient power loads (think offshore supply vessel dynamically positioning next to a drill rig in rough weather).”

The Orca product line consists of two distinct ESS platforms—Orca Energy and Orca Power—each using different battery cell technology with optimized performance characteristics to match high energy demands or high power demands, respectively.

Selecting ESS for High Energy or High Power
Let’s briefly revisit the terms energy and power, which are sometimes used interchangeably … but which are distinctly different. Energy is the “capacity for doing work”, while Power is the “rate of doing work” or the rate at which energy is consumed. The basic unit for energy is the joule (J), while the basic unit of power is the joule per second (J/s), known as the watt (W).

In terms of an ESS for marine vessels, the stored energy or capacity of the ESS is typically measured in kilowatt-hours (kWh) or megawatt-hours (MWh) meaning how much power can be delivered for a specified amount of time.

But, as Puchalski describes, as important for selecting the right ESS is the variability of the load—or demand for power—throughout the vessel’s operation profile and the time that the energy stored in the ESS is being discharged. Is the load relatively constant so that the ESS discharges evenly over time, as in a ferry on a fixed route crossing or an ESS used as battery-backup? Is peak demand intermittent and well above average demand, such as a tug that may spend less than 10% of its time at or near its full bollard pull rating? Or are there transient power loads, such as an offshore supply vessel using thrusters for dynamical positioning to maintain its position next to a drill rig?

Orca Energy ESS is optimized for energy storage uses with a relatively constant power load and discharge rate. It is ideally suited for use with all-electric short haul vessels, and is a viable alternative for spinning reserve, uninterruptible power supply (UPS) or fault ride-through for the entire power system or for subsystems. Due to high energy density, Orca Energy ESS offers a low cost per kWh of stored energy.

Orca Power ESS is an ideal energy source for uses with variable demand. It is designed for seamless response to dynamic power loads, and can deliver power quickly and efficiently to port cranes, charging stations, and offshore supply, exploration and production vessels. Due to extremely high C-ratings, Orca Power ESS offers the industry’s fastest discharge and charge rates.

Economic Benefit Improved with Correct ESS Matching
By correctly matching the appropriate ESS for the operating profile of the vessel and the intended use of the ESS, the economic payback is greatly enhanced—often doubling the return on investment.

In hybrid systems, the primary sources of an ESS’s economic benefit are reduced fuel consumption and lower generator maintenance cost due to efficient operation of fuel-based generators. An ESS can be used for spinning reserve, for instant response to transient loads, and for load balancing through peak shaving and ramping of dynamic loads where there is high variation in propulsion loads. These ESS functions allow generators to run less often and at optimal load for optimum fuel efficiency—resulting in reduced fuel consumption of 15%-75% depending on the application.

Further, the ESS can replace a generator and its associated capital, operating, and maintenance costs when used in fully electric vessels or in hybrid vessels for backup power, including spinning reserve.

Whether Orca Energy is selected for its high energy density and low cost per kWh, or Orca Power is selected for its high discharge/charge rates and dynamic response, Orca ESS is a practical and economical solution for an increasing number of marine applications. Since its introduction in June 2016, Orca ESS has been selected for over two dozen projects totaling over 20MWh, and the technology will only continue to improve the viability of these systems in a greater range of maritime applications.

Safety at Sea is the Top Priority for Corvus Energy Orca™ ESS

Safety at Sea is the Top Priority for Corvus Energy Orca™ ESS

Will safety be compromised as more and more battery vendors and marine propulsion system integrators bid to win a share of the expanding sea of hybrid and electric marine vessels? Corvus Energy, the leader in marine Energy Storage Systems (ESS), has worked hard to achieve the highest standards of safety with its Orca™ ESS, and is the only supplier to carry DNV, Lloyd’s Register, ABS and BV product Type Approvals.

Today is the Day of the Seafarer. In salute to seafarers, and out of intrinsic concern for their safety at sea, we want to review the design practices that Corvus Energy incorporates and the tests we have passed to prove the safety of the Orca™ ESS for hybrid or fully electric propulsion systems.

Geoff Crocker, Director of Product Management & Technical Sales at Corvus Energy, spoke at Nor-Shipping, and David Lokhorst, Corvus Energy’s Vice President of Engineering, spoke at Electric & Hybrid Marine World Expo about the safety features built into the company’s Orca ESS. For those who may have missed the presentations, this article captures the highlights.

The top three technical advancements that improve safety in Corvus Energy’s latest Orca ESS product line are:

  1. Thermal Runaway (TR) Protection
  2. Thermal Management
  3. Electrical Safety and Performance

Thermal Runaway Protection
The best protection from thermal runaway comes from prevention, by selecting a high quality cell manufacturer and designing the battery system with a sophisticated battery monitoring system (BMS), hardware safeties, and good integration with the energy management system (EMS).

However, in the highly unlikely event that a cell fails and its temperature spikes, it is important that adjacent cells do not also experience thermal runaway.

Corvus Energy’s Orca energy storage system design achieves true cell-level thermal runaway isolation, meaning that adjacent cells stay cool without the need for expensive active cooling. Further, The Orca ESS module is designed with internal ventilation pathways to vent gases generated by thermal runaway, and prevent gas from entering the battery room.

Orca ESS passed the NMA’s thermal runaway propagation Test 1—the most stringent test—in September 2016, witnessed by class society DNV GL. The NMA requires tests to verify that when safety systems are deliberately defeated and thermal runaway of a battery module is induced by overcharging, the thermal runaway is limited to a single module and does not spread to other modules in the battery pack. Corvus demonstrated that Orca was designed with a higher level of fault tolerance by eliminating the possibility of thermal runaway spreading to neighbouring cells within a single module.

Thermal Management
The Orca ESS design is optimized for heat-shedding to maintain a uniform temperature across the cell, which enables the cell to operate at its maximum capability. The design incorporates integrated rack fans and active temperature monitoring between cells, which improves reliability and reduces maintenance costs in the long run.

Improved thermal management also means that, typically, air-cooling is all that is required to satisfy marine demands and less battery room infrastructure is needed—both of which reduce system costs.

Orca ESS can also be liquid-cooled in extreme environments and ultra high performance use cases.

Electrical Safety and Performance
The clever and sleek design of the Orca ESS module-and-rack leaves no exposed cables for increased safety during installation and operation. Even the optional air- or liquid-cooling systems are integrated into the rack, resulting in actively cooled connections. Fewer connections, a shorter conductive path, and cooled connections lead to higher reliability and performance, in addition to improving safety.

In addition, safety features incorporated into Orca ESS triggers disconnect at predefined loads, over-voltage or over-temperature. And with voltage isolation of 7.2kV, Orca ESS exceeds Class and Flag standards.

Improved Safety, Better Reliability and Performance, and Lower Cost
While safety is paramount and fundamental to the design of Orca ESS, some of the design features—in particular those for thermal management and electrical safety—also result in overall system cost-savings due to faster installation and lower cost battery room and fire extinguishing system costs. It’s a good Day for a Seafarer when you don’t have to compromise safety for affordability.

Below are highlights of the five key performance areas in which Corvus Energy’s Orca ESS excel:

  1. Two optimized platforms—Orca Energy and Orca Power. With two design platforms optimized for either high energy or high power, the right ESS characteristics can be matched to the operational profile of each particular application. Often, ESS system costs can be half that of a mismatched system. Learn more…
  2. Unparalleled energy density. Corvus Energy works closely with its battery cell manufacturer to take advantage of cells with extremely high energy density while not compromising safety. Orca Energy offers a compact design packing 1.6 MWh in volume equivalent to a 20’ container. As such, Orca Energy can delivers clean energy capacity at a low cost per kWh improving affordability for electric or hybrid-electric ferries, tug boats, cruise ships, yachts.
  3. Highest C-Rate in the industry. Orca Power is designed for seamless response to dynamic power loads, to deliver power quickly and efficiently to port cranes, charging stations, and offshore supply, exploration and production vessels at an attractive $/kW. Orca Power can discharge at peak rates of 15C and continuous rates of 10C, rates that simply cannot be attained by any other ESS supplier in the industry.
  4. Ease of installation and commissioning. Considerable design innovation went into making Orca ESS safe and quick to install. Its sleek, modular design has reduced installation connection and commissioning times are reduced by 80% and installation costs by up to 50%. In many cases, there is also significant cost saving in setting up the battery room, with simplified sprinkler, ventilation, and class/flag approvals.
  5. Safest in the industry. Corvus Energy is the only supplier to carry DNV, Lloyd’s Register, ABS and BV product Type Approvals and its Orca ESS exceeds Class/Flag standards. Safety features include cell-level thermal runaway isolation, thermal management with remote monitoring capabilities, and improved electrical safety. Learn more <<Safety at Sea is the Top Priority for Corvus Energy Orca ESS>>

AAM Wins Hybrid Passenger Vessel Contract

AAM Wins Hybrid Passenger Vessel Contract

February 13, 2017
All American Marine, Inc. (AAM), inked a deal for the construction of a new hybrid electric passenger vessel to be delivered to the Red and White Fleet of San Francisco, California.  The contract for the new 600 passenger aluminum monohull was signed during the recent annual Maritrends Conference put on by the Passenger Vessel Association.
AAM’s latest contract follows an earlier announcement made by the company regarding a construction agreement for a 500 passenger aluminum monohull tour boat for Argosy Cruises of Seattle, WA.  Both operators were originally pursuing construction contracts for steel monohulls, but AAM was successfully able to demonstrate considerable savings in construction and maintenance costs with an aluminum design, while ensuring delivery of a robust and solid hull structure.  These contracts bode well for AAM, which is celebrating its 30th anniversary and is in the process of moving into a brand new purpose-built ship building facility at nearby Squalicum Harbor.  Argosy will take delivery of their vessel in the late fall and the Red and White Fleet will receive their new craft in the late spring of 2018.
The new vessel for Red and Fleet, to be christened, Enhydra, will be the first aluminum hulled, Lithium-Ion battery-electric hybrid vessel built from the keel up under US Coast Guard subchapter-K passenger vessel regulations and the latest guidelines for structural fire protection.  The vessel will be 128’ long with a moulded beam of 30’ and is specifically designed for harbor tours of San Francisco Bay and the Golden Gate Bridge.  Guests on board Enhydra will be able to experience amazing views of the bay and cityscape from each of the three decks, complete with their own convenient snack bar.  The second level offers a full wrap around viewing deck with access to the enlarged bow foredeck, which is sure to become a favorite photo spot.  The top deck is completely open and offers plenty of outdoor seating for sun soaking or respite from the busyness of the city.
All American Marine partnered with BAE Systems (BAESY) to design and integrate the complete battery electric hybrid system.  BAE Systems will supply their HybriDrive Propulsion System that includes a generator, control system, and AC electric traction motor.  The generator will mount to a variable speed Cummins (CMI) QSL9 410 mhp@2100 rpm diesel engine.  The motor generator offers diesel-electric operation of the AC traction motor which is coupled directly to the propulsion shaft.    With this configuration, torque is immediately available for the propeller and the speed can be precisely controlled without the need for a reduction gear.
The hybrid system will also utilize battery power from two 80 kWh Lithium-ion battery packs.  The batteries will come from Corvus Energy and are supplied under their next generation Orca Energy line.  The BAE HybridDrive system can automatically utilize full electric battery operation at slower speeds and when maneuvering in and out of the harbor.  At higher speeds, the generator will automatically engage and augment the additional power demands of the traction motor.  The battery system is sufficient to meet the entire demand of the vessel’s hotel load while at the same time providing silent and emission-free operation of the propulsion system during an evening sunset cruise.  Red and White Fleet’s Vice President of Operations, Joe Burgard, expressed “We are very pleased with the team All American Marine has put together to deliver this unique vessel and are eager for our guests to experience San Francisco Bay from the silent decks of the Enhydra in 2018. We see the propulsion configuration on the Enhydra as phase one in our move toward the full electrification of our fleet. Stay tuned for phase two.”
All American Marine Inc., located on the shores of Bellingham Bay, was founded in 1987 and specializes in the construction of custom tailored aluminum boats.  Today, the company has become a leading builder of high speed passenger catamarans, monohull tour boats, survey craft, and research vessels.  All American Marine is the exclusive builder for Teknicraft Design Ltd. catamarans in North America.
Founded in 1892, the historic Red and White Fleet is legendary for its premier San Francisco Cruises. Family owned, the Red and White Fleet is committed to environmental sustainability and community education as one of the oldest businesses operating in the San Francisco Bay area.

New Battery System for Shanghai Port Cranes

New Battery System for Shanghai Port Cranes

The Maritime Executive


By MarEx 2017-02-09 18:50:52

Corvus Energy will provide newly-designed lithium-ion energy storage systems for a hybrid rubber-tired gantry crane (RTG) designed by CCCC Shanghai Equipment Engineering.

The new solution, being taken up by Shanghai Zhenhua Heavy Industry, the world’s largest port crane manufacturer, is a smaller, ultra high power, liquid cooled system designed specifically to meet the RTG power requirements more cost effectively.

The first order is destined for Shanghai International Port Group and will be installed in Yidong Terminal, Shanghai.

Unlike conventional diesel electric port cranes, the CCCC hybrid version is powered primarily from the Corvus system resulting in fuel savings of up to 65 percent, says Corvus, with the added benefits of reduced operating costs with less greenhouse gas emissions and lower noise levels at the terminal.

Corvus makes industrial-grade lithium ion batteries that are used for making hybrid and electric ships, offshore drill rigs and port equipment. These batteries are combined into the diesel-electric drive trains of these industrial vehicles. The benefits are similar to the Prius and Tesla cars, (i.e. lower fuel consumption and emissions, better responsiveness and lower maintenance costs), but on a much larger scale because the industrial equipment has greater energy demands and generally work around the clock.

Gantry cranes are typically inefficient, running a diesel genset at full RPMs regardless of how much work they are actually doing. Therefore, during waiting, or low activity periods, a lot of fuel is wasted, says Corvus spokesman Sean Puchalski.

“Also, when they lower the containers, the electric motors spin backwards and generate energy. In a typical crane, this energy is wasted into heat by running it through a large resistor bank. The heat dissipates into the environment.

“Adding the battery helps in two ways: 1) it allows a smaller diesel engine to be installed, which saves fuel; and 2) the battery collects the energy from container lowering, for re-use, instead of wasting it. This improves fuel consumption.”

In addition to battery hybridization, some gantry cranes are being connected to the electrical grid to get completely off diesel gensets. This results in very good fuel cost improvements and also emission reductions, says Puchalski. However, this approach requires a large capital outlay for the electrical distribution and also reduces the mobility of the cranes.

The same types of technology are deployable around the globe. However, there are three main factors spurring the adoption of batteries in port equipment: 1) higher fuel prices; 2) busier ports; and 3) concerns about climate issues. These factors are strongest in China, Northern Europe and California at the moment, and this is where we will see the greatest early adoption, says Puchalski.

Stenersen's hybrid chemical tankers will feature energy storage solutions from WE Tech and Corvus

Stenersen’s hybrid chemical tankers will feature energy storage solutions from WE Tech and Corvus

Norwegian ship owner Rederiet Stenersen is building what are claimed to be the first tankers to feature hybrid electric propulsion, with WE Tech and Corvus Energy set to deliver the energy storage solution.

The owner is building two 17,500dwt chemical tankers (with an option for two more) at Taizhou Kouan Shipbuilding Co in China. The vessels will employ a direct drive permanent magnet shaft generator and an energy storage solution from WE Tech. Power generated through the shaft or supplied from shore connections will be converted to electricity and stored in a Corvus Orca Energy lithium-ion battery pack.

“As far as we are aware, Stenersen is the first company to have installed such equipment on this type of vessels,” said John Stenersen, director ship management, Rederiet Stenersen.

Stenersen noted that WE Tech’s Energy Storage Solution can be used as a spinning reserve to avoid black-out and to decrease the usage of generators on low load during manoeuvring. It can also be used for peak shaving, eliminating the need to start additional generator sets for short increase in loads and ensuring optimal running condition for online generator sets.

“Both situations create us savings from reduced generator running hours,” Stenersen added.

Halvard Hauso, senior vice president business development, Corvus Energy said: “This latest order from WE Tech Solutions shows the viability of energy storage for the hybridization of longer-haul vessels. As the cost of lithium ion batteries continues to improve we will see more and more applications beyond the traditional ferry and tug base.”

The first vessel, newbuild TK1201, is due for delivery in the first quarter of 2018. Steel cutting began on 10 November 2016. The WE Tech and Corvus equipment will be delivered in the second quarter of this year.
